The enzymes secreated by gram positive bacteria are called exoenzymes. They often serve to degrade polymeric nutrients that would otherwise be too large for transport across the plasme membrane.
Exoenzymes are enzymes that act outside of the cell that produces them, typically to break down large molecules into smaller ones before they can enter the cell. Endoenzymes, on the other hand, function within the cell that produces them to catalyze chemical reactions involved in various cellular processes.
Bacterial exoenzymes splits larger molecules into smaller ones , utilizing water in the process. The smaller molecules are then assimilated by the cell to be acted upon by endoenzymes to produce energy and cellular material
Casease is an enzyme that is formed by some bacteria that decomposes casein and is used in ripening cheese. Amylase is any of a group of enzymes that catalyze the hydrolysis of starch and glycogen or their intermediate hydrolysis products.
Polysaccharides are very large and therefore would require a lot of energy in order to transport across a cell wall. So cells will secrete exoenzymes to break the polysaccharides into smaller, monomeric portions and then absorb the monomeric portions in order to save energy.
Erythrogenic
In the clear area that would not be found in the blue area of starch agar plate after the addition of iodine is glucose and exoenzymes. Exoenzymes mainly hydraulic enzymes that leave the cell and breakdown.
Exoenzymes participate in chemical reactions outside of the cell, where they break down larger molecules into smaller ones that can be taken up by the cell for energy or other purposes. These enzymes are typically secreted by the cell to digest substrates in the external environment before they are imported into the cell.
what may be the uses of amino acids produced in gelatin hydrolysis by the pathogens that secrete this exoenzyme
Exoenzymes are digestive enzymes that are secreted by the pathogen into the surrounding tissues, allowing the pathogen to further invade the host's tissues. For example, Streptococcus pyogenes secretes streptokinase to dissolve blood clots, allowing wound invasion, and streptolysin, which digests red blood cells and other body cells. Clostridium perfringens, an agent of gangrene, secretes a lipase that damages cell membranes, creating more dead tissue for these bacteria to invade.

Endoenzymes work inside a cell. Exoenzymes work outside a cell after being secreted. Amylase is an exoenzyme because it's function is to break down starches in the mouth and GI tract. If it were an endoenzyme it would not function in this capacity.

Some bacteriamay form a slime layer. Bacteria that are covered with this loose shield are protected from dehydration and loss of nutrients. Despite their looseness,slime layersnevertheless play important roles in the attachment of bacteria to surfaces.Slime layerscan also bind cells together, and can trap nutrients and water, acting, for example, as a seal over a nutritious substrate, thus allowing a bacteria to use exoenzymes (extracellular enzymes) in a limited area containing high concentrations of substrate.So basically, slime layers can contribute to bacterial growth, which can result in food spoilage or affect food preservation.
